Residual resistance in the superconducting phase below T c . (a) Magnified view of Figure 2 around T c . The broken circles indicate the presence of residual resistances below T c . (b) Temperature dependence of the I-V characteristics of sample S1 below T c . The data are plotted in the log-log scales. The measured temperatures are indicated in the graph. (c) Red dots show the sheet resistance determined from the low-bias linear region of the I-V characteristics of sample S1. The blue line shows the result of the fitting analysis using Equation 6 within the range of 2.25 K<T<2.61 K while T c =2.64 K is fixed.
